NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-container package and not the kernel-uek-container package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

io_uring: fix possible deadlock in io_register_iowq_max_workers()

The io_register_iowq_max_workers() function calls io_put_sq_data(), which acquires the sqd->lock without releasing the uring_lock. Similar to the commit 009ad9f0c6ee ("io_uring: drop ctx->uring_lock before acquiring sqd->lock"), this can lead to a potential deadlock situation.

To resolve this issue, the uring_lock is released before calling io_put_sq_data(), and then it is re-acquired after the function call.

This change ensures that the locks are acquired in the correct order, preventing the possibility of a deadlock.
